Possibility of building a time machine with 可能

先生(せんせい):

「タイムマシンを作(つく)る事(こと)は私(わたし)は可能(かのう)だと考(かんが)えています」

“I believe it is possible to build a time machine.”

Key Points

1. 可能(かのう) = “possible” in a formal, theory-focused sense

   • Here, 可能(かのう)だ presents time-machine construction as something the speaker considers feasible, not just imaginable.

2. 作(つく)る事(こと)は = “as for building one”

   • 「タイムマシンを作(つく)る事(こと)は」 turns the act of building a time machine into the topic of the sentence.

   • The sentence is not about the machine itself, but about the possibility of the act of making it.

3. Ⓐは 可能(かのう)だ + と 考(かんが)えている

   • The core claim is 可能(かのう)だ.

   • 「と 考(かんが)えています」 softens it into “I think…” rather than stating it as an objective fact.

4. Spoken emphasis on topic with repeated は

   • The line says 「事(こと)は 私(わたし)は 可能(かのう)だ」.

   • That extra 私(わたし)は is a spoken way to emphasize “as for me, I think it’s possible”.
